Chez la veuve Duchesne|A Paris 1784|12 x 19.50 cm|4 volumes reliés
Second edition, rare, illustrated with 7 folding plates containing several figures on heavy paper, including a table showing different mercury measurements according to altitude.
Contemporary full glazed marbled calf binding. Smooth spine decorated. Havana morocco title label, green morocco volume label. Blue marbled edges. Top headcap of volume 1 worn with upper joint at head exposed, a lack at head of volume 3. 6 corners bumped with one exposed on volume 1. Handsome copy nevertheless, very fresh.
After studying geology, of which he was an eminent pioneer, Deluc devoted nearly 20 years of research to the study of atmospheric phenomena, particularly to determining heights using
a barometer. It was with this in mind that he set his sights on Mont Buet, which he attempted to climb 3 times with his brother. True pioneers of mountaineering, they reached the summit on September 22, 1770, accompanied by their measuring instruments (barometer, thermometer, hygrometer, etc). The account in this work of the high mountain excursion is one of the first testimonies on mountaineering. The volumes present all the experiments conducted at high altitude on boiling water, the barometer, air expansion, etc...
